Application and Future Trend of Advertising LED Display in Metro

　　With the progress and development of technology, the image quality of LED display screen is becoming more and more high-definition and delicate, overcoming the problems of low brightness and high gray, breaking the access control that LED display screen can only be used in the outdoor field, and has also been widely used in the field of indoor engineering display, including subway advertising.

　　Among numerous advertising media, indoor subway advertisements have the characteristics of concentrated traffic and high attention, which can improve consumers' awareness of products and brands. Compared with traditional outdoor advertisements, subway LED display advertisements are closer to consumers and can attract more attention. What are the applications of LED display in subway station advertisements?

　　The first is our common light box screen in the track area, which is suitable for the advertisement display of the subway track. The main audience is waiting passengers. The light box screen in the track area requires high pixel density, can be installed before maintenance, and has been treated by EMC, and has the ability to protect against moisture, water, corrosion, earthquake, etc.

　　The second is the advertising screen on the rail platform, which is applicable to the advertising display on the subway booth floor. The advertising screen on the platform is relatively close to viewing distance, and interacts with consumers through two-dimensional code and body sensing technology, so it has high requirements on contrast, refresh rate, gray scale and other parameters.

　　The third is the lobby LED display, which is applicable to the advertisement display in the subway entrance hall. The product is usually wall mounted and needs a wide viewing angle to meet the needs of consumers for close and wide viewing.

　　The standard configuration of modern metro lies in perfect hardware facilities and population size. With the addition of human body sensing devices, the subway advertising LED display can even change from one-way communication between consumers and LED display to two-way interactive communication, thus increasing deeper communication between more advertising audiences and advertising merchants, improving higher advertising efficiency, consumption conversion and traffic locking! In addition, with the rise of artificial intelligence, this will also be the trend of LED advertising with higher value in the future!
